fix(oceanbase-ce): update reconfigure script to argv-reading

[weicao]

Problem

PR #2862 changed the OBCE reconfigure action script from argv-reading ( with placeholder) to env-scanning (). This broke reconfigure on KB 1.2+, which delivers reconfigure params as argv via:

• in InstanceSet spec
• ()
• iterates pairs, each → one action call ()
• appends arguments to command argv ()
• Result: sh -c "script" -- system_memory 2G → =system_memory, =2G

The env-scanning script finds no matching env vars → no reconfigure parameters found in kbagent environment → exit 1.

Root cause confirmation

Edward (KB controller team) traced the full code chain and confirmed:

• KB 1.2 passes reconfigure params as argv, not env
• The env-scanning pattern was introduced by PR fix(oceanbase-ce): read reconfigure params from kbagent env #2862 (commit 78f66c03)
• PostgreSQL sibling addon uses the correct argv pattern: sh -c 'script "$1" "$2"' --

Fix

Clean revert of commit 78f66c03 — restore the original argv-reading pattern.

Before (broken):

env_file="/tmp/oceanbase-reconfigure-env.27563"
trap 'rm -f "$env_file"' EXIT
tr '\0' '\n' < /proc/self/environ > "$env_file"
# ... 20+ lines of env-scanning loop ...

After (fixed):

/scripts/{{ .script }} "$1" "$2"

Validation

• Smoke: 6/6 PASS (cluster creation, SQL read/write, service)
• O05 Reconfiguring: SUCCEEDED in 3s (was stuck 176min with env-reading)
• Controller log: successfully reconfigure the pod
• InstanceSet argv proof: reconfigureArgs: [["system_memory", "2G"]]
